The introduction of the Stop Online Piracy Act (SOPA) in US Congress caused a wave of dissent, anger, and protest over the possible censorship and gatekeeping of the Internet. To bring needed attention to this law, a large number of sites took down access to their websites and replaced them with messages or warnings about the potential effect of SOPA. On January 18, 2012, these one of a kind pages provided an insight into crowdsourced protest and collective action. As a result of this and other work, SOPA lost support and faded.
Archive Team has assembled a collection of WARC-format pages from that day. The collection can be browsed here
